Moving into my house, I discovered the attic only had about R20 insulation in the attic. Since that is where most of your heat loss is, I decided to get quotes to add insulation to R50. Great Northen submitted a quote and given their price and the reviews I read, I decided to go with them. That is one of the best decisions I have ever made. They went above and beyond my expectations and I would recommend them to anyone, and believe me, I'm fussy. This is a company that sure knows how to give customer service. I particulary want to thank Ben Mendonca, Ross Martin and Dave Rocha and Bernie for their great work and assistance. Also, thanks Susie for your help.
